Abstract
The high pressure compressor part of a gas turbine installation having a high pressure, a medium pressure and a low pressure part (21 and 22, 23) of the gas turbine is provided by a pressure wave machine in which the high pressure gas is generated by self-ignition of liquid or gaseous fuel, which is injected or blown into the cell rotor in the region of the low pressure air port from the fuel nozzles in a casing of the pressure wave machine. The self-ignition occurs as a detonation when the fuel impinges on a compression wave occuring in the region of the fuel injection. The pressure waves occuring generate, on the one hand, high pressure air in the zones (B) and (C), which are fed through a high pressure air port to a combustion chamber for the generation of driving gas for the gas turbine. On the other hand, the pressure waves generate a medium pressure driving gas and a low pressure driving gas in a zone (D) during the advance of the cells of the rotor in the rotor space, which gases are fed via ports into the casings or the medium pressure and the low pressure part of the turbine.
